Description

Technical Field

[0001] This utility model is a car suspension rubber bushing with a multi-directional buffer structure, belonging to the technical field of car suspension rubber bushings. Background Technology

[0002] Rubber bushings for automotive suspensions are commonly used in suspension systems to provide torsional and tilt flexibility and to control axial and radial displacement, serving as damping and vibration isolation functions.

[0003] Chinese patent CN118775474A proposes a rubber bushing structure for automotive suspension. By pulling a second handle, the sliding column, limiting plate, and limiting post move upward, releasing the limiting post from the limiting hole and sealing shell, and allowing the sealing shell to slide out from between the inner and outer tubes, thus completing the quick disassembly of the sealing shell. However, this design lacks a limiting and locking device for the second handle. If accidental contact causes the limiting post to disengage from the limiting hole, the sealing shell may fall off, posing a certain safety hazard and reducing its practicality. There is an urgent need for an automotive suspension rubber bushing with a multi-directional buffer structure to solve the above-mentioned problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a car suspension rubber bushing with a multi-directional buffer structure to solve the problems mentioned in the background art. This utility model has a reasonable structure, which facilitates the disassembly of the fixing seat and the inner tube, while locking the movement of the limiting block to prevent accidental contact. It is highly practical.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a car suspension rubber bushing with a multi-directional buffer structure, comprising an outer tube, a fixed seat, an inner tube, a rubber bushing, a limiting block, a sliding cavity, a rotating ring, a sliding block, and a ball head. Fixed seats are provided at both ends of the outer tube, an inner tube is provided inside the outer tube, a rubber bushing is provided inside the inner tube, a limiting block is provided inside the fixed seat, a sliding cavity is provided inside the fixed seat, a ball head is provided inside the fixed seat, a rotating ring is rotatably provided on the outer side of the fixed seat, and a sliding block is provided inside the rotating ring.

[0006] Furthermore, a rotating groove is provided on the outer side of the fixed base, and the rotating ring slides tightly along the inner wall of the rotating groove. Two sets of rotating rings of the same size are provided, and the two sets of rotating rings are fixedly connected by an operating protrusion.

[0007] Furthermore, the fixed base has a sliding groove inside, and the inside of the sliding groove is connected to the inside of the groove, and the sliding block slides tightly along the inside of the sliding groove.

[0008] Furthermore, the fixed base has a through groove inside, the sliding groove is connected to the inside of the sliding cavity through the through groove, and the sliding block is provided with a stop block in a clockwise direction. The stop block passes through the through groove and extends into the inside of the sliding cavity.

[0009] Furthermore, the sliding groove has a cavity inside, the ball head is disposed inside the cavity, and a return spring is disposed inside the cavity. The two ends of the return spring abut against the ball head and the inner wall of the cavity, respectively. The lower end of the sliding block has a ball groove, and the ball groove and the ball head are engaged with each other.

[0010] Furthermore, the limiting block slides tightly along the inner wall of the sliding cavity, a connecting rod is provided at the upper end of the limiting block, a handle is provided at the upper end of the connecting rod, a compression spring is sleeved on the outer side of the connecting rod, and the two ends of the compression spring abut against the limiting block and the inner wall of the sliding cavity, respectively.

[0011] Furthermore, a limiting groove is formed on the outer side of the inner tube, and the limiting block engages with the limiting groove. A groove is provided on the inner side of the inner tube, and a convex ring is provided on the outer side of the rubber bushing. The groove and the convex ring engage with each other.

[0012] The beneficial effects of this utility model are as follows: This utility model provides a car suspension rubber bushing with a multi-directional buffer structure. Because this utility model adds a limiting block, a limiting groove, a rotating ring, a sliding block, a stop block, and a ball head, the limiting block and the limiting groove engage with each other to fix the position of the inner tube and the outer tube. Then, the user drives the rotating ring to rotate clockwise by operating the convex plate. At the same time, the rotating ring drives the sliding block to rotate together. The sliding block drives the stop block to enter the sliding cavity through the through groove and abut against the upper end of the limiting block, thereby preventing the limiting block from moving upward and thus locking the limiting block. At the same time, the ball head and the ball groove engage with each other. Only when the external force of rotating the rotating ring is sufficient to overcome the elastic force of the return spring and cause the ball head to retract into the cavity and no longer engage with the ball groove can the rotating ring move.

The sliding groove 22 is connected to the interior of the sliding cavity 6 through the through groove 221. A stop block 82 is provided on the sliding block 8 in a clockwise direction. The stop block 82 passes through the through groove 221 and extends into the interior of the sliding cavity 6. After the stop block 82 enters the interior of the sliding cavity 6, it can abut against the upper end face of the limiting block 5, thereby preventing the limiting block 5 from retracting into the interior of the sliding cavity 6. A cavity 91 is provided inside the sliding groove 22. A ball head 9 is provided inside the cavity 91. A return spring is provided inside the cavity 91. 92. The two ends of the return spring 92 abut against the ball head 9 and the inner wall of the cavity 91, respectively.

[0024] As a second embodiment of this utility model: When the user installs the inner tube 3, the limiting groove 31 is aligned with the limiting block 5 and inserted, and the handle 61 is pulled upwards, so that the limiting block 5 is retracted into the sliding cavity 6. When the inner tube 3 is completely inserted into the outer tube 1, the compression spring 51 drives the limiting block 5 to reset, so that the limiting block 5 and the limiting groove 31 are engaged with each other, thereby fixing the position of the inner tube 3 and the outer tube 1. Then, the user drives the rotating ring 7 to rotate clockwise by operating the convex plate 71. At the same time, the rotating ring 7 drives the sliding block 8 to rotate together. The sliding block 8 drives the abutment 82 to enter the sliding cavity 6 through the through groove 221 and abut against the upper end of the limiting block 5, so that the limiting block 5 cannot move upward, thereby locking the limiting block 5. At the same time, the ball head 9 and the ball groove 81 are engaged with each other. Only when the external force of rotating the rotating ring 7 is sufficient to overcome the elastic force of the reset spring 92 and the ball head 9 is retracted into the cavity 91 and no longer engaged with the ball groove 81 can the rotating ring 7 move.
